Description

Clean Room Wall System {CLEANROOM WALL SYSTEM}

Clean rooms are industrial spaces that are constructed and maintained to maintain a room free of contaminants that interfere with the precise work that is done there. For example, clean rooms are used to produce certain electronic and computer components.

Components of a clean room wall system generally include studs to which the wall panels are fastened. The framework of the vertical studs and interconnected horizontal studs provides sufficient stability throughout the wall system. Wall panels can be arranged in several ways. For example, the panel may be a relatively thick member (hereinafter referred to as thick panel) that matches the nominal wall thickness and exceeds or equals the width of the stud to which the panel is fastened. Alternatively, a pair of thin, spaced panels (spaced to match the nominal wall thickness and referred to as "double wall") can be fastened to the stud.

In another embodiment, a single thin wall panel is fastened to one side of the stud and the opposite side of the stud is exposed. In this "single sidewall" arrangement, it is often necessary to provide the same nominal wall thickness as provided by the arrangement.

In recent years, the use of clean rooms has increased significantly. In addition, existing cleanrooms often require rearrangement or remodeling to accommodate changes that occurred in or near the cleanroom production system. The construction and remodeling needs are met very well with clean room wall system components that minimize the time and cost associated with the construction and assembly of the wall system as a result of construction.

The invention relates in particular to the construction and assembly of the components that make up a wall system well suited for clean rooms.

The present invention provides, due to its general configuration, a clean room wall system comprising stud components that allow the use of studs with various wall panel arrangements.

The studs are designed to easily and firmly support the batten aligned with the studs and serve to fasten the wall panels to the studs.

Connector blocks are also provided. The connector block is shaped for mounting at the end of the horizontally oriented stud and for connecting with the vertical stud in such a way as to ensure a secure engagement between the two studs. And a pair of connector blocks are employed to connect together two axially aligned studs, such as, for example, two vertically oriented studs. The butting aspect of the connector block enables simple configuration and remodeling of the wall system in the case where only a portion of the wall of the wall between the ceiling and the floor needs to be changed.

In addition, corner studs are also provided which are simply designed for the use of the universal wall studs of the present invention.

A new deflection track assembly is provided to connect the top track of the wall panel to a conventional ceiling grid to allow deflection of the grid relative to the wall panel and to facilitate access to the ceiling portion above the wall panel.

A preferred embodiment of a stud 20 formed in accordance with the present invention is shown in FIG. 1, which is an enlarged end view. The stud 20 is preferably extruded aluminum. The studs include outer walls 22, 24, 26, 28 that are rectangular in cross section and sized to form a relatively narrow side 32 of the wide side of the stud, which is represented by dimension 30 in the figure.

Slot 34 extends along the length of the stud to interrupt each of the four outer walls of the stud. Immediately inside each slot 34, the outer wall and the continuous inner wall 36, 38 are shaped to form a chamber 40. The slot 34 and the continuous chamber 40 in the opposing wide walls 22 and 26 taper towards the center of the stud. As will be described below, the inner walls 36 and 38 form two parallel portions in which the opposing surfaces 42 are corrugated to receive the threaded fasteners. The inner walls 36, 38 are connected by webs 37 extending in a direction generally parallel to the wider side of the stud at the center of the stud.

One of the inner walls 36 has a pair of extensions 44 extending into the chamber 40 towards the outer wall 28. This extension has a corrugated inwardly opposing surface 43, such as the surface 42 just described. The chamber associated with the remaining narrow side wall 24 does not include a corrugated surface.

Immediately within the outer wall forming each slot 34, the stud wall is shaped to form the shoulder 46. For each chamber, there is a pair of spaced and parallel shoulders. The shoulder pairs are spaced at a distance slightly larger than the width of the slot 34 and provide a surface on which the channel nut is supported, as described in detail below.

At each corner of the studs 20, as described below, the wall is shaped to form an almost closed hole for receiving the thin plate screws used to attach the connector block.

Each slot 34 in the outer wall has a pair of inwardly protruding ribs 50 that are slightly thinner than the wall. As a result, the outer wall has a recess for each slot, thereby receiving the cover 82 when the adjacent chamber is not used (see FIG. 4). The cover 82 seats in the slot such that the outer surface of the cover 82 is substantially flush with the stud wall.

A pair of ridges 52 are associated with each of the three chambers 40, which include corrugated surfaces 42, 43. In particular, the elongated ridge 52 extends parallel to the length of the stud on both sides of the slot 34 (ie, perpendicular to the plane of FIG. 1). For the purpose of fastening the wall panels to the studs, the ridges 52 mate with grooves 66 of corresponding shapes formed on the baton 60 (see FIG. 2) supported on the outer wall of the one or more studs 20. . It will be understood that this pairing occurs with a groove supporting the ridge and a stud supporting the baton. Ridge 52 also mates with a groove formed in connector block 100 (see FIG. 3) as described below.

Referring again to FIG. 2, baton 60 is a thin wall, extruded aluminum member, generally having a U-shaped base 62. The underside 64 of the base rests on the outer surface of the outer walls 22, 26, 28 of the stud and includes the groove 66 above. Groove 66 mates with ridge 52 on the stud thereby facilitating proper positioning of the baton in the stud when the baton is attached to the stud.

Since the base 62 of the baton 60 rests on the outer wall of the stud 20, the overall width of the stud and baton combination represents the sum of the widths of the two components.

Baton 60 also includes an outwardly extending flange 68. As a result, a gap 70 (see FIG. 3) is formed between the bottom surface 72 of the flange of the baton and the stud outer wall to which the baton is attached. As is apparent, wall panels or glazings can fit in this gap.

Holes 78 are formed through the base of the baton at positions spaced along the length of the baton. The hole 78 receives the shaft of the screw 80 (see FIG. 3). Screw 80 is screwed between corrugated surfaces 42 and 43 to fasten the baton to the stud.

At the center of the batten, a slot 74 is formed between the flanges 68 with a pair of inwardly protruding ribs 76 mating with the ribs 50 of the stud slot 34. As a result, one of the covers 82 is fitted into the baton slot 74 and covers it (see FIG. 3).

The parallel walls of the base 62 form a pair of shoulders 77. The shoulder pair 77 is spaced a little wider than the width of the slot 74 and provides a surface on which the channel nut is supported as described in detail below.

In some aspects, it is noteworthy that the stud components shown in FIGS. 3-5 are somewhat simplified for clarity of illustration. Reference should be made to FIGS. 1 and 18 when the details of the stud configuration need to be discussed.

3 illustrates the universal stud 20 of the present invention for use in at least three different wall configurations. In particular, the components of the system are assembled such that the two battens are mounted to the studs on the opposing walls 22, 26 forming the wide side 30 of the stud 20. As a result, the overall thickness of the wall fastened to the combined baton and stud (as measured between the bottom at the top of FIG. 3) is the sum of the width of the narrow side 32 of the stud and the two gaps 70. The sum is represented by the dimension "W" in FIG. In a preferred embodiment, this sum is a nominal wall thickness of 2 inches (5.08 cm).

As shown on the left side of FIG. 3, a conventional thick wall panel 84 is fitted in the flange 68 of the baton and held therebetween. This panel is in contact with the stud 20. As shown on the right side of FIG. 3, wall panel 84 may be mounted on studs 120 that are horizontally connected. The horizontal stud 120 has the same cross section as the stud 20 described above.

3 shows one arrangement whereby a pair of thin and spaced wall panels 86 ("double sidewall" arrangement above) are placed between the baton flange 68 and the outer walls 22 and 26 of the stud. It is held in each gap 70 present. The connector block 100 and the horizontal stud 120 are shown in FIG. 3, described below.

Referring to FIG. 3, it is noteworthy that the distance between the outermost edges of the flange 68 of the baton (ie, measured horizontally in FIG. 3) is about 3 inches in the preferred embodiment shown. However, it is noted that shorter flange baton may be employed. For example, a flange edge-to-edge distance of two inches is sufficient to leave the appropriate extension of the flange to secure the wall panel between them.

Compared with FIG. 3, FIG. 4 shows that the rectangular stud 20 is rotated 90 degrees to accommodate another wall panel arrangement—using the same stud design—which illustrates the overall aspect of the stud. will be.

In particular, FIG. 4 shows the baton 60 mounted to the wall 28 of the stud forming the narrow side 32 of the stud. (To show how the channel nut 83 fits into the stud and the baton, the fastener 80 that fastens the baton to the stud is not shown in FIG. 4). Only one side of the studs 20, 120, for example, It is covered with a thin wall, which may be 0.25 inches thick. As a result, nominal wall thickness (here 2 inches) is maintained even if the wall configuration requires such a single wall arrangement.

It will be appreciated that the use of universal studs 20,120 to assemble at least three different wall arrangements greatly simplifies the construction and handling of the components.

5-8 are useful for illustrating the configuration and use of the connector block 100. One preferred connector block is shown in FIGS. 16 and 17, which are shaped for mounting on the end of the horizontally oriented stud 120 and are vertical in such a way as to ensure a secure engagement between the two studs. Shape for connection with studs.

The connector block 100 includes a body 102 (Figs. 5, 16, 17) having a cross section sized to fit the cross section of the stud. Thus, the outer surface of the connector block body is at the same height as the outer surface of the stud 120.

The pair of protrusions 104 extend from one side of the block body. The protrusions 104 are spaced apart from each other and each of them is formed to slide into the chamber 40 of the stud. As shown in FIG. 6, the outside of each protrusion is slip fit between the opposite edges of the slot 34 of the combined chamber. The outer surface of the protrusion 104 as well as the outer surface of the body 102 are flush with the outer surface of the stud.

The cube cutout 108 is made in each corner of the block body 102 side opposite to the protrusion 104 side. The corner has a hole 109 passing through the sheet metal screw 112 (FIG. 5) and a head 110 recessed in the cutout 108. As shown in FIG. This screw is screwed into a hole 48 made in the stud as described above (FIG. 1). Thus, the screw 112 firmly attaches the block 100 to the end of the stud. The slip fit protrusion 104 in the stud slot 34 further strengthens the connection. The connection to the stud end is made of blocks whose cross-sectional area is no larger than the cross section of the stud.

An elongate recess 106 is formed on the side of the connector body opposite the protrusion (FIG. 5). The block surface also has a pair of parallel grooves 166 that are adapted in size and orientation, with grooves 66 formed on the lower portion 64 of the baton 60. Thus, as well shown in FIG. 4, when the horizontal and vertical studs are installed together to make a joint, the connector block groove 166 pairs with the ridges 52 on the studs 20 so that the correct Facilitate alignment

The connector block 100 includes two spaced holes 129 to receive a cap screw 103 (FIG. 6). When the block is fastened to the stud by the sheet metal screw 112, the shaft of the screw 130 extends from the block recess 106 and the head of the screw fits into the chamber 40 at the stud.

Channel nut 83 (top view, FIGS. 9 and side view, FIG. 10) is screwed to the exposed end of each screw 130 (FIG. 5). As such, the assembly of the horizontal stud 102 and the connector block is prepared to be coupled to the vertical stud 20. 6-8 show how the connector block 100 of the present system is connected to the end of the stud and with another stud by positioning the cap screw 130 and screwing the channel nut 83 onto the shaft of the screw. Show how it's connected.

The channel nut 83 is rotated enough to allow it to pass through the slot 34 and inserted into the chamber 40 of the stud 20. (The nut 83 in the right half of FIG. 5 is shown before this rotation.) Once inserted, the nut rotates until it is supported against the shoulder 46 so that the screw 130 is fully connected. As firmly as possible (see FIGS. 4 and 13). 11-13 are a series of three diagrams illustrating the just described method of connecting one stud 120 with another stud 20 oriented perpendicular to the first stud.

Baton 60 and stud 20 are sized such that a single size of channel nut 83 can be used to connect the studs (as just described) and to connect the article to the baton. With respect to the latter, FIG. 4 shows a channel nut 83 that fits into the baton and is adapted to receive an end of a threaded fastener that can be used, for example, to connect a shelf to a wall panel.

It is noteworthy that the recess 106 in the connector block 100 is sized to receive the channel nut 83 screwed onto the scoop 130. In this regard, the nut may be retracted into the recess 106 so that it does not protrude from the block. This retracted position is shown in dashed line in FIG. 8. The retraction shape reduces clearance requirements in assembly (because the unconnected beam and connector block assemblies are no longer than the connected beam and connector block assemblies) and therefore, for example, before fixing the horizontal studs to the vertical studs, Very easy movement of the horizontal stud into position between the studs.

As noted above, a pair of connector blocks can be employed to connect with two aligned studs, such as two parts of vertically oriented studs. The connection aspect of the connector block can simplify the structure and can simply remodel the wall system if only the wall portion between the ceiling and the floor needs to be changed.

As shown in FIGS. 14 and 15, this connection is achieved by abutting the ends of two studs 20 with connector block 100 fastened in the manner described above. In one embodiment, one of the blocks is modified by threading a normal clean hole 129. Once the studs are aligned, the screws 130 passing through one block are screwed into correspondingly threaded holes on the remaining blocks to secure the connection. The screw 130 may have an allen-type head for tight fit with an allen winch that fits through an adjacent slot 34 in the stud.

The present invention has been described in terms of preferred embodiments. It will be appreciated that the present invention can be changed by a person skilled in the art by changing or supplementing the elements.

For example, FIG. 5 shows the connection of the narrow side of the vertical stud to the narrow side of the horizontal stud along the appropriate connector block. Substantially similar connector blocks can be used where a wide connection of a vertical stud to a wide side of a horizontal stud is required. However, this block can be changed finely so that the recess 106 extends in parallel to the short side of the block. Thus, the protrusion 104 can be realigned to fit into the appropriate chamber at the stud.

18 is an end view of a stud component of a wall system formed in accordance with an alternative embodiment of the present invention. In many respects (eg, universal side width), the stud 220 is substantially similar to the stud 20 of FIG. 1. The last two digits of the three digit reference number that applies to FIG. 18 correspond to the reference numerals of similar components described with respect to FIG. 1.

The embodiment of FIG. 18 includes more metal at the corner 227 compared to FIG. 1. The hole 248 is spaced about one diameter away from the outer corner wall of the stud. This improves the stud's resistance to deflection along this length along the thick vertical and horizontal parts of the inner walls 236 and 238 (ie, horizontal and vertical as shown in FIG. 18).

FIG. 19 shows one side of a connector block 300 for use with the stud embodiment of FIG. 18. Except for the area surrounding the hole 309 for the sheet metal screw, this block substantially coincides with the block 100 described above. These holes 309 are centered with the holes 348, further away from the corners of the stud 220 as shown. As a result, the hole 309 is countersunk in the surface 310 of the block, thereby eliminating the need for the cube cutout 108 described above. The head of the sheet metal screw 112 is placed in the countersink portion of the hole 309 invisibly.

20 and 21 show end views of corner studs 320 designed for use with the device. Referring first to FIG. 20, the corner stud 320 includes a planar web 322 extending through the corner stud. The web is formed integrally with the rest of the stud (as by extrusion) and is at an angle of 45 ° with respect to the vertical walls 324, 3 26 joined by the corner stud 320.

Corner stud 320 also includes an inner angle member 328 and an outer angle member 330. The inner angle member is an overall 90 ° angle member with a vertex at the connection of this member and the web 322. Thus, the inner angle member is divided into two vertical portions, one portion 332 extends to one wall 326 connected and the other portion 334 extends to the other wall 324 connected.

The outer angle member 330 is an overall 90 ° angle member with a vertex at the connection of the member and the web 322. The outer angle member is thus divided into two vertical parts, one part 336 extending to one connected wall 326 and the other part 338 to the other connected wall 324.

The ends of the inner angle portion 332 and the outer angle portion 336 away from the web are formed in the side wall 3410 with the connector slot 300 (FIG. 19) fixed and having a central slot. For this purpose, the side walls are provided with a pair of ridges 342 mating with the grooves 366 of the connector block. Each end of the outer angle portion 336 and the inner angle portion 332 is provided with the shoulder portion 346 inside the side wall 340 on the opposite side of the slot. As noted above for the other studs, the shoulder portion 346 provides a support surface for the channel nut 83 that allows the connector block 300 to be secured to the corner studs 320 via screws 130.

The ends of the other portions 334, 338 of the inner and outer angle members are formed so that the attachment of the connector block 300 coupled with the other wall 324 is possible to match that shown.

With respect to the outer angle member 330, each of the portions 336, 338 includes a concave portion 348 comprising two parallel portions, the opposing surface being provided to accommodate the threaded fastener 350. I am connected. The fastener 350 extends through the spaced holes of the baton 60 to fix the batten to the vertical portions 336 and 338 of the outer angle member 330. As noted above, the slot of the baton can be closed with a cover 82.

The connected rounded edge of the flange 68 of the baton 60 is supported by the protrusion 352 of the web 322. The protrusion extends from the apex of the outer angle member 330 and ends in a 90 ° arrowhead shape and is fixed against the edge of the baton flange 68.

The web 322 also extends inward from the apex of the inner angle member 328 and extends toward the wall 326 parallel to the edge of the flange 68 of the baton mounted to the outer angle member 330. Form an inclined flange member with The spacing between the flange 68 and the web flange portion 354 matches the wall thickness of 2 inches (5.08 cm) described above. As a result, the walls 324, 326 connected by the corner studs 320 may be any of three wall shapes, such as those described above (“double sidewalls” shown in FIG. 20).

FIG. 21 is a diagram of a corner stud 320 showing connected walls 360 and 362 applied to the "single sidewall" mentioned above. The view of FIG. 21 also differs from the view of FIG. 20 because the view of FIG. 20 shows walls 324 and 326 connected adjacent to the connector block 300 in cross-sectional form. However, FIG. 21 shows the walls 360 and 362 connected at a position away from the connector block across the liner 364 in cross-section, which is described next.

The liner 364 is a long, plastic member having a box-shaped cross section as a whole. The liner 364 is useful for covering the sidewalls 340 of the corner studs 320 (or for covering the sidewalls of the studs 20, 200). In this regard, one side of the liner is open and formed of two curved tabs 367. The outermost end of the tab 367 fits through the slot 368 of the sidewall 340. When the liner is pushed against the sidewall 340, the tabs deform toward each other, and then the connection of the relatively narrow tab once returns and the liner reaches the slot 368. As a result, the elasticity of the tab 367 secures the liner 364 against the wall 340, as shown in FIG. 21.

The liner 364 shown in FIG. 21 is shaped to be fixed between the flange portion 354 of the web 322 and the wall panel 369. As shown at 370 of FIG. 21, the liner is placed on a corner stud 320 that is oriented vertically between the connections with a horizontal stud. In this arrangement, the liner counters the inner deformation of the panel 369 relative to the corner stud 320. The liner can also be formed to fit any other wall structure.

22 shows a front view of the vertical double wall 400. The top of the wall is covered with a long top track 402. The top track is a rigid, overall box-shaped member that includes a central slot 404 at the bottom one of the two horizontal walls. A shoulder portion 406 is formed inside the slot 404. The shoulder 406 is for the channel nut 83 which allows the fastening of the connector block 300 (supported on the end of the stud 20 facing vertically) to the top track 402 via the screw 130. Provide a support surface.

The sidewall of the top track includes protrusions 408 that are spaced to the wall thickness. The top of the wall 400 is fitted between the protrusions. The upper horizontal wall 410 of the top track 402 includes a separate (unscrewed) through hole 412, which facilitates connection with a ceiling grating or other structure, as described in more detail below.

In keeping with the general characteristics of most of the components of the present invention, the bottom track 414 for covering the bottom of the wall 400 is identical in structure to the top track but must be flipped over for use. The section of the wall 400 in the floor track 414 covers the slot 404 of the floor track 414 between the connector blocks used herein and another liner 416 against deformation inward of the wall panel 418. ) Is selected at a location that describes the embodiment (ie, away from connector block 300).

In some cases it is desirable to connect the top track 402 of the wall to the ceiling grating in a manner that allows relative movement (slight deformation) of the ceiling grating relative to the wall. To this end, the apparatus is provided with a deflection track assembly, details of which are described in FIGS. 23 to 24.

The deflection track assembly 500 is for connecting the top track 402 of the wall to the ceiling grid. The ceiling grating is rigid and includes a pair of prolonged prongs 502 that do not move towards or away from each other, although being subjected to some vertical strain (vertical considered in FIGS. 23 and 24). Above these prongs 502 may be attached a ceiling grating mount, such as an illumination 504, which sometimes requires access.

The deflection track assembly includes a clip 506 that is a generally U-shaped member with a body 508 in which two legs 510 extend. Leg 510 forms an end with a hook adapted to the shape of ceiling prong 502. The clip 506 is simply attached to the prong 502. This linkage is snap-fit, so that one hooked end of the leg 510 close to one side of the prong (FIG. 23) is moved between the prongs 502, and the hooked end of the other leg 510 is The legs 510 are slightly pressed against each other until they are pressed upwards against the round bottom of the other prong 502 and then the hooked ends of both legs fit between the ceiling prongs. Thus, one clip 506 is attached without using a tool.

Once the clip is in position (i.e., the position hooked to prong 502), the U-shaped base member 520 as a whole is attached to the clip. Base member 520 is attached to the clip by fasteners 522. In this regard, the bottom 508 of the clip includes a recess 509 in which the shaft of the fastener 522 is located.

Base 520 includes a bottom surface 524 formed to include a pair of shoulders 526. Shoulder 526 provides a support surface for channel nut 83 that allows securing top track 402 to base 520 via elongated screws 528 (FIG. 24). (Screw 528 is not vertically aligned with clip screw 522).

The leg 530 of the base 520 is aligned with the clip leg 510 and has a length such that the end 532 of the leg 530 is supported against the ceiling prong so that the leg 530 and the clip leg 510 are supported. This prong is held between the hooked ends of the. Thus, the device connecting the base 520 to the clip 506 also locks the interlocking prongs and hooks together.

As described, the holes 412 of the top track 402 are not threaded. Thus, when the ceiling grating is deformed downward (this deformation is transmitted to the screw through the connected clip and base), the head end of the screw, as shown by the dashed line in FIG. Free movement against

Base 520 is formed to support baton 540 that closes the variable gap between top track 402 and base 520. In this regard, the opposite side of the base is formed with a central corrugated slot 544 and a continuous concave channel 542 (FIG. 23). Baton base 544 (FIG. 25) fits into the channel and is secured through screws 546 as shown in FIG. 24. Preferably, one of the flanges 548 bends slightly inward to ensure sliding engagement with the sidewall of the top track 402. That portion of the flange 548 that is in contact with the top track 402 (and therefore sometimes slides against it) may be covered with a low friction material 550 such as polytetrafluoroethylene coated tape. The other flanges of the batten, such as the ends 532 of the legs 530, are supported against the ceiling prongs, thus enhancing the restraint of these prongs between the legs 530 and the hooked ends of the clip legs 510.

As described, the length of the deflection track assembly 500 (measured perpendicular to the plane of FIG. 24) is chosen short (e.g., 2 inches) and is spaced several apart to connect the top track 402 to the ceiling grid. It is noteworthy that the assembled assembly is employed. Size and spacing facilitate access to the ceiling attachment, so that once one or both batons 540 are removed there is sufficient clearance between the two assemblies 500 and between the top track 402 and the ceiling prong 502. . For example, the lighting attachment 504 can be replaced without having to remove the deflection track assembly from either the ceiling grid or the top track.
